Grisel Santiago is worrying about summer gas prices. This Bronx resident is hoping to take her family of five on a surprise road trip in July. But since she has no idea what prices will be like in a few months, she’s economizing every which way she can now.

“It’s ridiculous. We cut back on everything — even toilet paper, 16 rolls for $20. Buy less and less than what you use to get,” Santiago said.

But why on one strip in Yonkers, where there are three gas stations with three very different prices — the most being $4.35 for regular and the least at $4.19, are there any takers at all at the most expensive place? Clearly it’s capitalism at work and what the market will bear.

“Because we are full service. We here 23 years. People like us,” station owner Vitu Kumar said.

“I try to use just one gas station with this kind of car. My husband says use this. It’s quality I’m looking for,” Mobil customer Ruth Dempster said.
